Chemical Description

  • Butyl Acrylate (BA) is an organic compound categorized as an ester, which is formed from acrylic acid and butanol. It is recognized by its molecular formula C7H12O2. This compound appears as a colorless liquid with a characteristic, slightly acrid odor and is notable for its low water solubility but high miscibility with a wide range of organic solvents.
  • Butyl Acrylate is widely utilized across numerous industries due to its ability to polymerize easily and form copolymers with other monomers such as methyl methacrylate, acrylic acid, and its esters. This versatility makes it a fundamental ingredient in the production of paints, coatings, and adhesives.
  • In the coatings industry, BA contributes significantly to the formulation of water-resistant and weathering-resistant paints, enhancing durability and finish quality. It's used in decorative and protective coatings due to its excellent adhesion properties and flexibility.
  • For adhesive applications, Butyl Acrylate provides superior adhesive strength, flexibility, and resistance to both UV light and chemicals. It's a key component in pressure-sensitive adhesives used in labels, tapes, and decorative films.
  • In the realm of textiles, BA enhances the finishing of fabrics by improving softness, wrinkle resistance, and durability. It's utilized in treatments that impart special properties to fabrics, such as water repellency.
  • Butyl Acrylate also serves as a plasticizer in the production of plastics and rubber, lending flexibility, durability, and improved performance characteristics to a variety of polymer products.
  • Furthermore, BA is employed in the manufacture of sealants and caulks, offering excellent weathering resistance, flexibility, and adhesion to a wide range of materials.
  • The polymerization of Butyl Acrylate can yield products that have applications in personal care products, offering properties such as film formation and moisture retention which are valued in cosmetics and hair care formulations.
  • In the paper and packaging industry, coatings and adhesives containing BA improve the quality and functionality of paper products, contributing to strength, gloss, and resistance to oil and grease.
  • Environmental considerations with Butyl Acrylate involve its volatility and potential to form vapors that could affect air quality. However, it is widely used in applications that benefit from its low toxicity and ability to biodegrade under certain conditions, aligning with efforts to develop more sustainable materials and processes.
